摘要
The present invention provides a new method to obtain an effective diffusivity for a certain substance in solutions that diffuse through a porous material. The porous material initially separates two solutions that are different in concentration of the substance. The concentration gradient gives rise to diffusion through the porous material, The concentration change of the substance in the low-concentration compartment is detected through a measurement of the electrochemical impedance data. By means of the measurement, an effective diffusivity coefficient of the substance through the porous material is calculated.
